摘要：
A process for the production of an optically active carboxylic acid (I), which comprises subjecting an olefinic carboxylic acid (II) to asymmetric hydrogenation using a complex as a catalyst consisting of an optically active phosphine (III) and a ruthenium compound.Complex of ##STR1## with a ruthenium compound ##STR2## According to the process of the present invention, optically active carboxylic acids can be produced with high yield.
